If the area of a circle is 324 cm, find:
Its circumference in terms of pi

​

Answers

Answer:

20.3π cm

Step-by-step explanation:

Area of a circle = 324 square cm

    πr² = 324

   [tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]

  r = 10.15 cm

Circumference = 2πr

                         = 2 *  π * 10.15

                         = 20.3π cm

     

Fifty less than four times a number is ten. What is this number?

Answers

Let the number be x.

The equation is:

4x - 50 = 10

=> 4x = 10 + 50

=> 4x = 60

=> x = 60/4

=> x = 15

So, the number is 15.

During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?

Answers

Answer:

2 or 200%

Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week,  6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week

Step-by-step explanation:

Perimeter of ΔABC = 12+ perimeter of ΔACD

Perimeter of ΔABC= AC+CB+BA

Perimeter of ΔACD=AC+CD+DA

DA ≅DB since there is a ⊥bisector trough D and

Therefore,

Perimeter of ΔABC= (AC+CD+DA)+BA = Perimeter of ΔACD +12 therefore AB=12

Amelia rented a dvd and it was due to be returned on 26 november

Nine more than the product of a number and 4 is equal to 7.

Answers

9+4n=7 is the equation


Explanation:


It’s saying product of a number and 4 so we would multiply 4 and a variable (I chose n) then it says nine more than that so you would add that to 4n then it equals 7.

Answer:

equation is 9+(4x) = 7

x = -0.5

Step-by-step explanation:

+ 9 to (4x) equals 7

9 + 4x = 7

4x = -2

x = -0.5

to prove:

9+(-0.5*4) = 7

9 + -2 = 7

7 = 7
